The Prince of Wales was told it was good luck after he trod in a cow pat at the Great Yorkshire Show.
Charles was inspecting some South Devon cattle at the Great Yorkshire Show in Harrogate, North Yorkshire, when he stepped in a dollop of bovine manure.
Anne Tully, from Brixham, Devon, was judging the show and told him: "I told him that was luck, that’s what we always say."
The prince, who attended the show with his wife Camilla, then came face to face with champion 1,550kg Hereford bull Moralee One Rebel Kicks, owned by Tom and Di Harrison from Stocksfield, Northumberland.
Mr Harrison said afterwards: "I could have talked to him for an hour.
"He is very knowledgeable and I would have liked to have bought him a pint."
Prince Charles visited the show days after revealing some of his favourite tracks, including Givin’ Up, Givin’ In by The Three Degrees.
The prince said the track used to give him "an irresistible urge to get up and dance".
Speaking on a pre-recorded hospital radio show to be aired at noon today, dedicated to volunteers of the Hospital Broadcasting Association, Prince Charles said the American soul music trio performed the 1970s hit at his 30th birthday.
Other tracks on his 13-strong list include La Vie En Rose by Edith Piaf, Upside Down by Diana Ross, The Voice by Eimear Quinn, The Click Song by Miriam Makeba, You’re A Lady by Peter Skellern, La Mer by Charles Trenet, Bennachie by Old Blind Dogs, Lulu’s Back In Town by Dick Powell, and They Can’t Take That Away From Me by Fred Astaire & Ginger Rogers, Tros Y Garreg/Crossing the Stone by Catrin Finch and Tydi a Roddaist by Bryn Terfel.
